How to deal with the seeds of wheat before sowing?

How to deal with the seeds of wheat before sowing? Please give us some instructions before sowing wheat seeds can be treated as follows: first, selected seeds are often irregular in grain size, and often mixed with damaged grains, grass seeds and seeds with diseases and insect pests before sowing. After sowing, the growth of wheat seedlings is inconsistent, which is easy to form weak seedlings and affect high yield. Therefore, carefully select the self-retained seeds before wheat sowing, remove damaged, disease and insect grains and sundries, ensure the seed texture, and lay the foundation for seedling integrity, seedling integrity and seedling strength. Second, the germination test must be carried out before sowing, to determine the germination rate and germination energy of the seeds, to avoid the poor emergence caused by the low germination rate, and to provide the basis for determining the appropriate sowing rate to ensure the whole seedling sowing. Simple seed germination test method: take two wheat seeds, each with 100 seeds, soak the seeds in 30 ℃ warm water for 3-4 hours, then take two vegetable plates without oil stains, each plate with 4-5 layers of toilet paper, then put the soaked seeds on toilet paper, cover 3-4 layers of toilet paper, and finally wet toilet paper with 30 ℃ warm water, put the germination plate in a warm place, and the germination rate can be counted after 3 days and nights. Third, drying wheat before sowing can prevent mildew and insect pests, promote seed ripening, break seed dormancy, improve germination energy and germination rate, which is beneficial to strong seedling and high yield. According to the experiment, the germination rate of sunburned seeds can be increased by 14-16%, with an average increase of about 15%. The time of drying seeds is generally 25-30 days and 7-10 days before sowing, in order to significantly improve the germination rate of seeds. Fourth, chemical seed dressing for self-retained seeds can use 0.3% phoxim and 0.1% triamcinolone acetonide to 8% water, mix it into a solution, spray it on wheat seeds, mix it evenly and pile it up for 8-10 hours before sowing. It has a significant effect on the control of underground pests and seedling diseases and insect pests. Click to get more wheat planting technology click to get more grain planting technology
